Application filed April 8, 1912. Serial No. 689,103.

To all whom it may concern:

Be it known that I, JOHN C. DE LANEY, a subject of the United Kingdom ofGreat Britain and Ireland, residing at Watertown, in the ounty ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Shaft-Couplings, of which the following is aspecification, reference being had therein to the accompanying drawings.

The'objects of my invention are :F irst, to provide means whereby abalanced shaft or a balanced arbor will remain balanced when power isapplied to it; and I attain this object'by the use of a drivingapparatus so designed as to apply the power to the driven shaft, equallyin opposite directions, atdiametrically opposite points having the sameradius from the axis of the driven shaft. Second, to so design saiddriving apparatus that the driven shaft or the driven arbor may, withoutbeing disturbed in relation to one of its bearing boxes, besimultaneously disconnected from the source of power, and moved into aconvenient and suitable position for mounting or demounting pulleys,rings, saws, cutting heads, molding heads, or the like. I attain thisobject, by mounting the driven shaft or arbor in a bearing box pivotedto a base or frame; and also by having the driving apparatus so designedthat when the driven shaft is swung upon itspivot, the driven shaft orarbor swings out of engagement with said driving apparatus, withoutdisturbing the driving shaft. This result will follow where the adjacentends of the driving and driven shafts have a rib and a slot that can beswung into or out of interlocking engagement when they are in the planeof the swing of the axis of the pivoted driven shaft or arbor.

In the drawings illustrating the principle of my invention and the bestmode now known to me of embodying the same in operative structure,Figure 1 is a perspective view showing my invention embodied in amolding machine, only a port-ion of which is illustrated; and also meansdropped down) employed in working up stock into various forms of moldingstrips, said means, however, forming no part of my present in vention.The pivoted arbor is shown disconnee-ted from its driving shaft, and hasbeen swung into a position for mounting, or demounting the moldingheads, saws, etc., some of which are being slid along the arbor. Fig. 2is a plan, partly in section, showing the pivoted arbor and its drivingconnections; the tops of the boxes having been removed. Fig. 3 is adetail view, partly in section, showing the driving connections andpivoted journal box of the arbor. Fig. 4 is an end perspective viewshowing the pivoted arbor and driving connections, in operativeposition, and a pivoted supporting bracket with adjustable guiding andsupporting devices mounted therein, partially dropped down out of normalposition, to permit the swinging forward and back of the pivoted arbor.Fig. 5 is a detail view showing the means employed for verticallyraising and lowering a portion of the bed of the machine upon which thejournal boxes of the pivoted arbor are movably mounted.

Arranged across the finishing end of a molding machine A, Figs. 1 and 4,is a vertically adjustable bed 1, Figs. 1 and 5, upon which are mountedarbor journal boxes 2 and 3. To give the desired vertical movement tothis bed, a shaft 4, Fig. 5, is horizontally mounted in the machineframe 5-, and has thereon under each box, a bevel gear 6, which mesheswith a corresponding bevel gear 7 having a vertical stem 8 turning inand passing up through the frame, and into the base of the bed 1; theholes in the base, and the free end of the stem being suitably threaded.A crank 9, Fig. 4., may be applied to one end portion of this shaft;and, obviously, by turning it, the bed 1 may. be raised or lowered whileit is in horizontal planes. The journal box 2 rests, and is movable,upon the top of an end portion of the base, about a vertical pivot 10,Fig. 3. This pivot is a threaded bolt extending up through the base intothe bottom of the box, where it engages a corresponding thread in thelower portion of a box binder. By turning the binder handle 11 in onedirection, the box 2 becomes bound to the bed 1, between the head 12 ofthe bolt 10 and the portion of the binder handle bearing against the topof the box 2; by turning the handle in the opposite direction, the boxbecomes sufficiently freed to permit the box to be swung upon the base,around the bolt or pivot as shown in Figs. 1 and 2. The other box 3 ismovable transversely of the machine, upon the op'posite portion of thebase;

there being a T-slot 13, Figs. 1, 2 and 4, in

the top' surface of this portion, engaged by i the head of a bolt whichpasses up through the box 3, and has its threaded end portion engaged toa box binder 14, similar to that, 11, just described in connection withthe pivoted arbor box 2. To bind this box 3 to the frame, with thegreatest rigidity,the rear portion of this box bears against a backsupport 16, Fig. 2, on the frame of the machine, and is there secured bya lock bolt 17 and nut 18, Fig. 2, in slidable engagement with a slot19, Fig. 1, in the back support 16. To give additional rigidity to thepivoted box and the frame of the machine when in operative position, useis made of a slotted bolt 20, Fig. 2, passing through an opening in achannel back 21, and a block 22; and a pivot pin 23 passing through theblock 22, and the slot in the bolt; while a head 24 suitably threaded ismounted upon the free end of the bolt which is correspondingly threaded.In the upper portion of the back 25 of the box 2, Figs. 1 and 2, is avertical slot 26,

Figs. 1 and 2, to receive the shank of the bolt; the head 27 of the boltengaging the outside of the slot. lVhen the parts are in normal positionand the head 24 is turned up, they bind the pivoted box 2 and the 2frame rigidly together; when the head 24 is partially unscrewed from thebolt 20, the latter slides longitudinally upon the pivot pin 23, andpermits the head 27 and the bolt to rise out of the slot 26, this beingbrought about by the weight of the block 22, and the head 24 actingdownward around the pivot pin 23; and the pivoted box is free to swingupon its pivot 10, as in Figs. 1 and 2. Mounted in these journal boxesis an arbor 28, Figs. 1 and 2, for the reception of molding heads B andsaws C. It has rings 29, Fig. 2, formed thereon to engage correspondingring cavities in the pivoted journal box 2 to prevent longitudinalmovement of the arbor in relation to the boxes. Its free end portion isslightly tapering, and has a corresponding bearing in the opposite box3- to facilitate the longitudinal movement of the box to free the arborfrom the box and permit the arbor to be swung upon its pivot in a mannerto be more fully explained hereinafter. That the power to drive thearbor 28 may be so applied as to twirl the arbor about its axis, thatis, not pull it around as in the case of. a belt and pulley upon anarbor, and further that the arbor may be pivoted, there is a drivingshaft 30, Figs. 1 and 2, mounted in suitable adjustable bearing boxes31, and driven by a belt 32 and pulley 33 thereon, together with drivingconnections secured to the adjacent end portions of the driving shaft 30and the arbor 28 to be driven. These driving connections consist of twomembers 34, 35, one having across its end portion a diametricallyarranged rib 36; and the other, a corresponding slot 37; there beingplay or back lash between the cooperating driving and driven points ofcontact of the rib and slot; the pivot of the arbor box being in such aposition that when the slot and the rib are in a plane at right anglesto the axis of the pivot, the arbor can be turned upon the pivot withoutinterference between the slot and the rib of the driving connections. Itwill be noted that by this construction, the power from the drivingshaft 30 is transmitted to the arbor 28 equally and oppositely atdiametrically opposite points equally distant from the axis of thearbor, and, in so far as the power is concerned, there is no tendency towear the arbor bearings unevenly, except that due to the weight of thearbor.

In order that the swing of the pivoted arbor 28, Fig. 2, may not beinterfered with, by a bracket table 40 with the various parts thereon,Figs. 1 and 4, the table is pivoted to the frame of the machine bypivots 41, Fig. 1, so that the table may be dropped down and out of thepath of the swinging arbor. To hold the table up in normal position, alock slot 42, Fig. 4, is provided in each of the arbor boxes 2, 3, and acorresponding slot 43, Figs. 1 and 4, in each end of the table, wherebya bolt 44 and nut 45, engaging these slots, may be tightened, firmly tosecure the table in operative position. This bracket 40, and its severalparts constitute no part of my present invention, and are described andclaimed in divisional application No. 702,117 filed by me June 6, 1912.

The molding heads and saws shown, and forming no part of my presentinvention, may be like those shown and described in United States PatentNo. 999,014, granted to me July 25, 1911, and they may be securedthereon as described therein.

The stock to be out up into strips of molding, as D, and the number ofstyles of strips to be made, having been determined, suitable heads andsaws may be selected and mounted upon the arbor. To do this the rib 36and slot 37, Figs. 1 and 2, in the driving conlock bolt 20 of thepivoted arbor box 2 must be loosened; as must also the box binder 14 andlock bolt and nut 17, 18, of the slidable arbor box 3; the bracket table40, disconnected from the arbor boxes 2, 3, by disconnecting the lockbolts 44 in the lock slots 42 in the side of the arbor boxes from theslots 43 in bracket table, so that it may be dropped down, out of thepath of movement ofthe swinging arbor. Next, the sliding arbor box 3 isdrawn away from the free end of the arbor, as shown in dotted lines inFig. 2.

The arbor may now be moved about its pivoted arbor box, the rib and slotof the connecting members becoming disengaged, see Figs. 1 and 2, andthe free end portion of the arbor presented to the operator, in aposition to easily receive in the proper order thereon, the moldingheads and saws. The arbor is next swung back into alinement with theaxis of the driving shaft; the rib and slot of the coupling members moveinto operative engagement; and the sliding arbor box may be pushed intoengagement wit-h the free end portion forming the bearing of the arbor.The boxes, and consequently the arbor, may now be secured absolutely inoperative position upon the base of the machine by turning up the boxbinders 11, 14, and lock nuts 18, 24. The axis of the arbor may beadjusted at the right height in relation to the bed of the machine, bythe lifting shaft 4, Fig. 5, and operated by the handle 9, Fig. 4. Next,the bracket table 40 is lifted up about its pivot 41, Fig. 1, andsecured in horizontal position by the lock bolts in the lock slots 42,in the boxes, engaging the lock slots 43 in the table, all of which withfurther matter appears in my said divisional application.

In fine, I have described new and useful means whereby an arbor may bebalanced and capable of being swung out of operative engagement with itsdriving shaft.

Desiring to protect my invention in the broadest manner legallypossible, what I claim is p 1. An arbor; a pivoted bearing box for saidarbor; a driving shaft; said arbor, bearing box, and driving shaft,having the same longitudinal axis when they are in operative position;and positive interlocking means to connect the driving shaft and thearbor in operative position, and to permit said driving shaft and arborto become engaged, or

tact, located diametrically opposite, having equal radii, and permittingthe driving shaft and arbor to become engaged, or to become disengaged,by swinging the arbor upon its pivot.

3. An arbor; a pivoted bearing box for said arbor; and a driving shaftthe adjacent end portions of said arbor and driving shaft being providedwith a rib and a slot; whereby the arbor may be swung into or out ofposition for the rib and slot to engage, for the purpose of operativelyconnecting or disconnecting the driving shaft and arbor.

4. An arbor; a pivoted bearing box for said arbor; the axis of saidpivot being a line not passing through the axis of the arbor but in aplane at right angles to this axis; and a driving shaft; the adjacentend portions of said arbor and driving shaft being provided with a riband a slot, whereby the arbor, when the rib and slot are substantiallyin a plane at right angles to the axis of the pivot, may be swung intoor out of position for the rib and slot to engage, for the purpose ofoperatively connectlng or disconnecting the driving shaft and arbor.

In testimony whereof I aflix my signature in presence of two witnesses.
